Ethanol and Clean Air: The "Reg-Neg" Controversy and Subsequent Events

The Clean Air Act Amendments (CAAA), enacted in 1990, called for cleaner automotive fuels in order to upgrade air quality. This appeared to provide new market potential for ethanol, which is obtained from corn grown in the midwestern United States, and which is already in large-scale use in a blend of ten percent ethanol to ninety percent gasoline. The CAAA left specific details of the clean fuels program to be worked out by the Environmental Protection Agency (EPA), in consultation with the interested parties.

High- and low-temperature bonding techniques for microstructures (open access)

High- and low-temperature bonding techniques for microstructures

The ability to bond together two or more silicon wafers greatly expands the variety and complexity of silicon microstructures that can be designed and fabricated. At LLNL, microstructures have been used for many years as hardware in scientific experiments. The activity has recently been expanded into other areas to include microinstruments for biomedical applications and for chemical analysis. Both high temperature (1100{degrees}C) bonding techniques have been used, depending on the application. This paper discusses these applications with emphasis on the most extensive which is the fabrication of microchannel coolers for diode arrays.
